For a Future to be Possible

Jim Hansen:

Why I must speak out on climate

'Imagine a giant asteroid on direct collision course with Earth. That is the equivalent of what we face now, yet we dither.'

James Hansen is Adjunct Professor of Earth and Environmental Sciences at Columbia University’s Earth Institute. He was trained in physics and astronomy in the space science program of James Van Allen at the University of Iowa. His early research on the clouds of Venus helped identify their composition as sulfuric acid. Since the late 1970s, he has focused his research on Earth's climate, especially human-made climate change. Hansen is known for his testimony on climate change to congressional committees in the 1980s that helped raise broad awareness of the global warming issue. He is recognized for speaking truth to power, for identifying ineffectual policies as greenwash, and for outlining the actions that the public must take to protect the future of young people and the other species on the planet.
